Q. 16.9 - An Introduction to General, Organic, and Biological Chemistry

Question

Give the name of the amino acid represented by each of the following abbreviations:

a. Ala

b. Q

c. K

d. Cys

Step-by-Step Solution

Answer

The amino acids that represent the given single letter abbreviations are as follows: 

(Part a). Ala-Alanine (A)

(Part b). Q-Glutamine (Gin).

(Part c). K-Lysine K

(Part d). Cys—Cysteine (C)

Step 1: Given data(Part a)

Give the ALA name of the amino acid represented by each of the abbreviations.

Step2: Introduction (Part a)

Amino acids are the building blocks of proteins. These contain one hydrogen atom, one amine group$\left(-{\mathrm{NH}}_2\right)$, one carboxylic acid group, $(-\mathrm{COOH})$and one side chain (R group) attached to the central carbon atom. Two amino acids are linked together by peptide bonds to build up proteins. Single letter and three letter abbreviations are used to denote amino acids in short hand.

Step 3: Explanation (part a)

(a). Ala-Alanine(A)

Step 4: Given data (part b)

Give the name of the  Q amino acid represented by each of the abbreviations.

Step 5: Explanation(part b)

(b). Q-Glutamine (Gin).

Step 6: Given data (Part c)

Give the name of the K  amino acid represented by each of the abbreviations

Step 7: Explanation (part c)

(c). K-Lysine(K)

Step 8: Given data(Part d)

Give the  name of the  Cys  amino acid represented by each of the abbreviations.

Step 9: Explanation(part d)

(d). Cys —Cysteine (C)
